Lucky 13

Nickname given, by the British scientists who identified it, to the thirteenth
known SNC meteorite. News of its identification
was announced on August 12, 1998. The object, about the size of a softball
and weighing 2.2 kg (4.8 lb) was found in the Sahara desert. It is important
because it appears to have come from a different part of Mars
and to be of a different age from the other known SNC meteorites. It is
also the only martian meteorite to have a private owner. Six of the others
are owned by the US government and six by museums.
